Windows start>shutdown> shows switch user|logoff|lock|restart|sleep. no hibernate. I ran powercfg.exe /hibernate on and verified that c:\hiberfil.sys is present. Is there a bios setting that would control this? The only power settings I see in bios are: ACPI SUSPEND S3; REMOTE WAKE UP ENABLED;AC RECOVERY POWER OFF; AUTO POWER ON DISABLED. Does one of these control hibernate?
